Congratulations to you both!!! Please email me at possibilities75@gmail.com (my personal email account which I will be using for job applications in the future ;)) in the next few days, so we can organise your photos. I'd love to get these completed and sent to you as soon as possible before Christmas.

Thank you so much to everyone who entered, I wish we could have given one to everyone. And a HUGE thank you to Tina for organising this. xxx
